Abstract: The present disclosure provides an electrographic toner and methods for preparing an electrographic toner. In particular, the present disclosure provides an electrophotographic toner comprising a latex, a colorant and a releasing agent. The electrophotographic toner may further comprise zinc (Zn), iron (Fe), and silicon (Si). The [Zn]/[Fe] ratio may be in the range of about 5.0×10?2 to about 2.0×10?2. The [Si]/[Fe] ratio may be in the range of about 5.0×10?4 to about 5.0×10?2. [Zn], [Fe] and [Si] denote the intensities of Zn, Fe and Si, respectively, as measured by X-ray fluorescence spectrometry.

Abstract: Provided are an electrophotographic toner, a process for preparing the same, image forming method and an image forming apparatus using the toner. The electrophotographic toner may include a latex, colorant, wax, Si and Fe. A molar ratio of Si/Fe may be about 0.1 to about 5.

Abstract: A toner having a cohesion level of 50 or less when measured using an ASTM D 6393-99 includes a first agglomerated toner including latex particles for a core, a pigment and an inorganic salt, and latex particles for a shell layer coated on the first agglomerated toner, wherein the latex particles for the core and the latex particles for the shell layer are prepared by polymerizing a composition including an amphiphilic monomer having a hydrophilic group, a hydrophobic group and at least one reactive functional group, and a polymerizable monomer.

Abstract: A reflector for a mobile terminal includes a plate having a front and rear side, such that the plate is configured to be located on a mobile terminal. The reflector further includes a recess formed in the rear side of the plate, such that the recess is shaped to form a concave portion, and reflecting material positioned along the concave portion to reflect light incident on the front side of at least a portion of the plate.

Abstract: A method of preparing toner, is provided by preparing a stabilizer dispersion solution using distilled water and a dispersing agent; forming droplets by discharging the toner composition including at least one polymerizable monomer, a colorant, wax, and an initiator into the stabilizer dispersion solution through a syringe needle; forming core particles by warming the droplets dispersed in the stabilizer dispersion solution; and forming shells by adding a polymerizable monomer, a cross-linking agent, and an initiator to the core particles. The diameter of particles of the toner can be efficiently adjusted by changing the manufacturing process of the polymerization toner. The distribution of the toner particle diameter is improved and thus no additional sorting process is required. Also, the transferring performance of the toner can be improved, and various colors can be realized by a simple process.

Abstract: A method of preparing toner is provided, including: forming polymer latex particles by polymerizing a toner composition including a macromonomer having a hydrophilic group, a hydrophobic group, and at least one reactive functional group, a polymerizable monomer, a chain transfer agent, and an initiator; aggregating the polymer latex particles; and separating and drying the polymerized toner. The polymerizable monomer is selected to produce at least two groups of polymer latex particles having different molecular weights, wherein the polymer latex particles are selected from the group consisting of a first latex polymer group having a molecular weight less than about 20,000, a second latex polymer group having a molecular weight of about 20,000 to 40,000, a third latex polymer group having a molecular weight of about 40,000 to 50,000, and a fourth latex polymer group having a molecular weight of about 50,000 to 100,000.

Abstract: A method of preparing toner and a toner using the method is provided. More particularly, a method of preparing toner controls a shape of finally obtained toner particles by adjusting a molecular weight and Tg of polymer latex and can easily obtain a desired size, shape, and size distribution of toner particles by controlling aggregation of polymer latex particles and process conditions. A toner using the method, an image forming method using the toner and an image forming apparatus including the toner are also provided.

Abstract: A method of manufacturing toner uses a simplified process, in which the use of a surfacant is reduced to minimize the amount of wastewater generated. The toner manufactured using the method, an image forming method using the toner, and an image forming apparatus employing the toner are also provided.

Abstract: Disclosed herein is a communication terminal which has an adequate structure for keys so as to sufficiently fulfill various communication services, to thereby make the communication terminal compact, and can control operation of the keys so as to minimize a data input error of the keys. The communication terminal includes a first housing, a second housing which is oppositely coupled to the first housing, and a control unit which interrupts operation of a data input part provided at either the first housing or the second housing according to movement of the second housing with respect to the first housing.
